STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on July 16, 2014 at 07:46Hi All,Using the standard Cube (F4 v1.30) HAL_SD drivers, I randomly get the SD_TX_UNDERRUN'' error when writing using HAL_SD_WriteBlocks().It happens totally at random.I have tried:- using older libraries - same resu...
Posted on March 03, 2015 at 20:35Hi ST Forum,I want to implement a DMA RS232 device (with a MAX232 transceiver), where if the master sends a certain message (e.g. 0x01), then the STM32 will send back a certain message (e.g. 0x02). I got the DMA Tran...
Posted on March 25, 2015 at 15:06I am having a problem getting an Adafruit FTDI Serial TTL-232 Serial USB adapter to work with USART1 on an STM32L1 processor. When the adapter is not connected to the processor, or when the processor is powered and i...
Posted on March 25, 2015 at 18:18Hi, i'm pretty new to Interrupt handling so maybe i forgot something. This is my code for Setting up PA0 & PA1 Input Pins. The pin state works fine:bool GetRegisterDdkSpurA() { return GPIOA->IDR & GPIO_IDR_IDR_0; } ...
Posted on March 25, 2015 at 18:09Hello, as i'm new to the Forum i say hello to everybody. My first issue is with the HAL-Can Driver. Although there should be enough bus capacity the Driver is sometimes busy for ~ 700 MS where i can not send out any ...

Posted on March 20, 2015 at 13:58I know DMA acts as a channel where the CPU gets bypassed while data is transferred between Memory/ Peripheral,and in the mean-time CPU can execute useful operations..But my question is ...If the DMA transfer is going...
